Results of Tool Steel H13, Remelted With SMS Mevac's GmbH's New-Generation Electroslag Remelting With Rotating Electrode Function

摘要

SMS group responds to the constantly increasing demands of the tool manufacturing industry continual innovations. The challenge was to choosing of the right innovation method for the development of the new generation of the ESR furnace, especially with the demand to reduce the melt pool depthless, to repress the carbide formation by accurate ingot crystallization during ESR process. Furthermore, the methods defines a specific objective for the implementation SMS group presents in this paper the innovation method ESR unit with rotating electrode function and implementation of this method for remelting of the tool steel grade H13 on the basis of the same principles of the conventional ESR process with rigid electrode. To find out the influence of a rotating electrode during the ESR process. SMS Mevac GmbH redesigned the atmospheric rigid mold ESR unit at the IME Institute for Process Metallurgy and Metal Recycling at RWTH Aachen University: its vertically oscillating function has been changed to a rotating and vertically oscillating function. This paper presents the results regarding the thinner slag skin, the molten metal pool formation for better crystallization accuracy, and the cleanliness of ESR ingots, which have been remelted with rotating electrodes.
